Hey!
I´m using CodeLite v2.0.3365 on MacOSX.
I just don´t get how to set up a project so that the folders of my svn project are shown in the workspace view.
I succesfully checked out the folder structure from my svn and created a project inside this repository. But all that is shown is a "src" folder with a file named main.cpp in it. What i want to in contrast is the folder structure from my svn. Could somebody help me?

If I understand you correctly, you checkedout the sources from the SVN to your local disk - this is not enough.
You also need to create a project (which you did, and from your description, you create a console application with main.cpp file.
The best way now is this:
right click on your project, and select 'import files from directory' and select the directory where your files are located.
Once this is done, you will have your sources in the workspace view.

Ok i tried to use "Import Files from Directory" but when i do this just nothing happens. I changed the root-directory to my local repository and said "Ok" but the only thing that happens is that a window pops up with a text like this "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" and closes immediadetly. No files are imported.
